Canon EF 12mm II Extension Tube

Canon EF 12mm II Extension Tube

Place this 12mm extension tube between your Canon EF camera body and lens to increase the distance from the lens to the sensor. That added spacing boosts magnification and reduces the minimum focus distance, making it a smart choice for close-up and macro photography.

The Canon EF 12mm II also keeps electronic communication between the camera and lens, so key functions remain available depending on lens compatibility. Because it contains no optical elements, it helps preserve image quality while giving you more creative control at short focusing distances.

Key Features

• 12mm extension tube for Canon EF and selected EF-S lenses
• Increases magnification for close-up and macro shooting
• Shortens minimum focus distance
• Maintains electronic contact between lens and camera
• Compact and lightweight design for easy transport

Usage Notes

Autofocus performance depends on the lens used. With some zoom lenses, autofocus may not be available. The amount of extra magnification is determined by dividing the extension length by the lens focal length.
